ENGLISH
With the Overdose alarm one can select a period during which the setpoint must be reached. If the setpoint is
not reached during this period of time, the instrument blocks output operations, including those in mA (metering
pumps), the alarm is displayed as ON and triggers a signalling instrument connected to the alarm relay.
Maximum Metering is an extra safety function that ensures metering is
completed in the selected time. This function makes it possible to eliminate
time limits (continuous metering according to the selected setpoints) or to
select the minutes (up to 999) and the hours, for instance metering for 999
minutes in 24 hours (see MAXIMUM METERING TIME menu).
The start-up delay stops the output relays when the unit is switched on, thus allowing the sensor to polarise
assuring correct measurements (programmable).
ONLY WHEN USING METERING PUMPS
The priming function blocks the setpoint value to allow the metering pump to
remain primed, the outputs are not active.

settings as the SETPOINT 1 menu, with the exception of the MIN/MAX Alarm
function, indeed only found in the SETPOINT 1.
